Can you guys do me a favour and render a video for me and post how long it takes your current system to do it? Posting your systems specs would be helpful too.

To keep things standardized can you use Window Movie Maker and the "Wildlife.wmv" file that is preloaded in Windows 7. (Libraries\Videos\Sample Videos)

I do a lot of video editing and this "real world" test will give me an indictaion of what are the better processors for this kind of task.

Thanks.

Unless you're using Windows Movie Maker to render the videos this really won't give you an accurate indication. Better to find reviews using the software that you actualy use to edit / render the videos.

Some programs perform better with more threads while others perform better with more CPU speed. You can see this by comparing the i7 3770K (8 threads @ 3.5GHz stock speed) & i7-3930K (12 threads @ 3.2GHz stock speed) using the link kleinkinstein supplied.

Artificial benchmarks are useful for a ball park estimate of what the processor's media rendering capabilities are. Besides that, you're asking for a specific scenario (Windows Movie Maker, with whatever codec and settings Microsoft uses, with a movie that's already been processed). The time it takes to render a movie depends on a lot of factors, including what you're rendering in the first place.

I also don't see any rhyme or reason why you're asking for this. Are you planning on getting a new system?

It's interesting to see the balance needed between # of cores and the GHz they run at.

I have a four core CPU @ the same 2.4GHz and it renders the same video in 1 minute 30 seconds.

Just for an equal IPC comparison, I disabled 1 core per FP on my Opteron so that it's now operating at 1 core per 1 FP instead of 2 cores per 1 FP then re-ran the test. Time with 4 threads @ 2.4GHz = 1 minutes 35 seconds. If you're only doing 1min 30sec on your current rig, any current generation i5 or i7 will be one hell of an upgrade for you. Even the 'low end' i5-3350 should match or beat my overclocked 1055t.

Thought I'd also share the results from the new processor... 27.5 secondsi7-3930K @ 4GhzMovie Maker only averaged 43% CPU usage & only used 9 of the 12 threads on the 3930k, but on the Phenom it's averaging 93% CPU usage & using all 6 available cores, so in theory, with 100% utilizaiton of all 12 cores on the 3930k??? 12 seconds???

So do you think that the 3930K's cores are more efficient than the Phenom's so they end up not needing 100% to do the rendering? Or is something else at play?

Considering the 3930K took longer, don't think it's efficiency related, but any thoughts I might have towards that end would be pure speculation. However, if I were in a speculating mood, I might speculate that Microsoft Movie Maker a) doesn't scale well past 6 cores b) has issues with X79 chipset or LGA 2011 processors c)disk access speed to low to utilize more than 8 cores effectively.

I can check out two of those: first I can setup a RAM drive for the file save to eliminate any possible write speed limitation. If that doesn't let Movie Maker run on all 12 cores, then I can disable HT so that there's only 6 cores for Microsoft Movie Maker to use & see if I then get similar results to the 1055t. If the first doesn't work & the second does then the issue is with Movie Maker itself i.e. poor scaling as core count increases. If neither works, then its likely a communication problem between Movie Maker & chipset or CPU, maybe a previously undetected bug in any of the 3.

I appreciate the thought but don't go to that kind of trouble for this.

For a comparison I ran the same test on my brother's 8 core AMD 8120 and the higest any of the cores got was around 85%. But all 8 were being used.

Did some playing around anyway due to curiosity... Save to ram drive got all 12 threads going, but still at only about 43% utilization. Dropping Hyper Threading actually resulted in a faster time of 24.7 seconds and an average utilization of about 72%.

If it wasn't for the blazing performance & 100% utilization for the entire clip render in Premier Pro, I might think that there's a driver conflict somewhere, & that could still be the case, but right now, it kind of makes it look like some sort of conflict between Movie Maker & the hardware.
